• Configuring a max-group value will have no affect on existing group memberships until the member-

ships are refreshed on the port/VLAN instance.

• The configuration is allowed even when the ip multicast status is disabled.

• If the num and action parameters are not specified, then the limit is removed.

• The max-group configuration on a specific VLAN or port will override the global configuration.

• MLD zapping must be enabled when the max-group limit is enabled and the action is dropped.
